The person who invented Chinese water torture was Hippolytus de Marsiliis. He was born in 1451 in Bologna, Italy and he died in 1529 in Italy. Hippolytus de Marsiliis was a lawyer and doctor utriusque iuris. He received his doctorate in 1480 but the date at which he became a lawyer is unknown. Throughout his life, he wrote many detailed catalogues and notabilia on many canons and decretals. In addition, he taught Roman law beginning in the year 1482.

Chinese water torture is a process in which water is slowly dripped onto the scalp, allegedly making the restrained victim insane. This form of torture was first described under a different name by Hippolytus de Marsiliis in the 15th or 16th century. He is accordingly credited with the initial invention of a true form of water torture. Having observed how drops of water falling one by one on a stone gradually created a hollow, he applied the method to the human body. Some suggestions say that the term "Chinese water torture" was invented merely to grant the method a sense of ominous mystery. Victim are stripped of their clothes, shown to the public in many cases, then plainly tortured. They have been driven insane while bystanders watch and mock them.
